What matters should be paid attention to in the use of cutting equipment for carton, color box, foam and KT board material template?

When using the cutting equipment for cardboard boxes, color boxes, foam and KT boards, it is necessary to pay attention to the following matters in combination with material characteristics and equipment operation specifications to ensure safety, improve efficiency and ensure cutting quality:

First, the preparation before equipment operation

Equipment inspection and debugging

Check whether the power cord and data cable of the equipment are in good condition, and whether the plug and socket are firm to avoid leakage or poor contact.

Make sure that the cutting tools (such as blades, laser heads, milling cutters, etc.) are firmly installed without looseness, wear or fracture, and select the appropriate tools according to the material type (such as foam is suitable for low-power laser or heating wire, KT board is suitable for art knife or numerical control cutting knife).

Debugging cutting parameters: Set the cutting speed, pressure (mechanical cutting) or power (laser cutting) according to the thickness and hardness of the material, so as to avoid material burning (foam, KT board), tearing (carton, color box) or incomplete cutting caused by improper parameters.

Clean the countertop to ensure that there are no sundries and oil stains, and place anti-skid pads (for light materials such as foam and KT board) to prevent the sliding of materials from affecting the accuracy.

Environment and safety preparation

The laser cutting equipment should be used in a well-ventilated environment, equipped with smoke exhaust devices to avoid the accumulation of harmful gases (such as formaldehyde and benzene series) generated by foam and KT board cutting, and the operators should wear protective masks.

Operating space should be reserved around mechanical cutting equipment (such as manual paper cutter and CNC cutting machine) to avoid collision caused by stacking sundries.

Operators should wear protective equipment: goggles when cutting foam/KT board (to prevent debris from splashing), non-slip gloves when using electric equipment, and special protective clothing when operating laser equipment.

Second, the cutting considerations of different materials

1. Cartons and color boxes (paper materials)

Avoid over-extrusion: paper materials are easy to deform, and the clamp pressure should be adjusted when cutting to prevent wrinkles from affecting the cutting accuracy.

Control cutting speed: High-speed cutting may lead to paper edge fuzzing, especially for corrugated boxes, so it is necessary to match the sharpness and speed of the cutter.

Prevention of electrostatic adsorption: cutting paper materials in dry environment is easy to generate static electricity, so anti-static spray or grounding device can be used to prevent paper scraps from being adsorbed on equipment or materials.

2. Foam (EPS, EPE, etc.)

Laser cutting needs to be flame-proof: foam is flammable, and too high laser power can easily lead to edge blackening or even fire. It is necessary to monitor the cutting process in real time and equip with fire extinguishing equipment (such as dry powder fire extinguisher).

Anti-fragmentation in mechanical cutting: When cutting hard foam (such as EPS) with a blade, it is necessary to keep the cutter sharp, so as to avoid material fragmentation caused by excessive force, and lightly scratch the cutting line in advance.

Debris cleaning: the debris generated by foam cutting is light and easy to fly, so it needs to be cleaned with a vacuum cleaner in time to prevent fire from being inhaled into the respiratory tract or accumulated.

3. KT board (foam core composite board)

Avoid surface damage: the surface of KT board is made of paper or plastic film, and the depth of cutting tool should be controlled to prevent the tip of the knife from cutting the surface (especially for display samples).

Anti-deformation of laser cutting: KT plate is easy to deform when heated, so laser cutting needs to reduce power, increase speed, or adopt sectional cutting to reduce thermal influence.

Prevent delamination: If the pressure is too high during cutting, the surface layer of KT board may be separated from the foam core, so it is necessary to adjust the cutter angle (such as 45 oblique cutting) or choose a special serrated cutter.

Third, the safety regulations in the operation of the equipment

Prohibit illegal operation

It is forbidden to look directly at the laser beam during laser cutting to avoid eye burns; When cutting mechanically, the hand should not be close to the running track of the tool, and auxiliary tools (such as push rod and fixture) should be used.

It is forbidden to adjust parameters, change tools or clean up waste materials when the equipment is running. Stop the machine and cut off the power supply first.

A clear division of labor is required for multi-person operation, so as to avoid touching the equipment control panel or materials at the same time and prevent misoperation.

Real-time monitoring and emergency treatment

Observe the material state closely during cutting: If you find any abnormality such as foam smoking, KT board surface melting, carton fire, etc., immediately stop the machine and cut off the power supply, and use corresponding fire extinguishing methods to deal with it (dry powder or carbon dioxide fire extinguisher shall be used for foam/paper materials, and water shall not be used to extinguish the electrical fire).

If the equipment has abnormal sound, vibration or peculiar smell, stop the machine immediately for inspection, and remove the faults (such as tool sticking and motor fault) before continuing to use it.

Fourth, the maintenance of the equipment after use

Cleaning and maintenance

Cleaning the cutter: remove the residual materials (such as foam chips and paper fibers) on the cutter in time, and wipe the laser head or blade with alcohol to maintain sharpness and accuracy.

Lubricating parts: the moving parts such as guide rails and bearings of mechanical cutting equipment need to be added with lubricating oil regularly to prevent rust or jamming.

Check worn parts: replace worn blades, saw blades or laser tubes regularly to avoid cutting quality degradation or safety hazards caused by equipment aging.

Material and waste disposal

After cutting, the samples should be classified and stored to avoid extrusion deformation (for example, KT boards and cartons should be laid flat, and foam boards should be protected from direct sunlight to prevent aging).

Centralized waste treatment: foam and paper waste should be recycled separately, and harmful waste generated by laser cutting (such as burnt foam) should be treated according to the standard of hazardous waste and should not be discarded at will.

summary

When using cutting equipment, it is necessary to match the equipment type and parameters according to the material characteristics, strictly follow the process of "inspection-standard operation-real-time monitoring-maintenance", and focus on preventing fire (foam, laser cutting), mechanical injury (cutter) and harmful gas (laser cutting), which can not only ensure the safety of operators, but also prolong the service life of equipment and ensure the quality of samples.
